Samsung A5 difference in charging with Marshmallow

I finally updated my A5 yesterday night to the most recent OS. But this morning i tried to charge my phone and after i plugged it in and turned it off, instead of it showing the charging screen with the green flow going towards the battery icon like I usually see, theres a single green flashing dot.
My phone also appears to be charging slower than it was before. I tried to look it up online but nothing came up. Is the change from flowing stream to single dot just a design change from Samsung with the update, or is it signalling something more serious?
